  The circulation type underfloor storage device shown in Patent Document 1 requires a large-scale work such as a rail installation work, and thus has a problem that the construction work is troublesome. In addition, even if you try to install the underfloor storage device later by remodeling etc., it is impossible to install rails in a narrow space under the floor, and in some cases, such as renovation etc. with troublesome work such as removing the floorboard There was also a problem that it was difficult to install retrofit.

  Moreover, since the underfloor storage apparatus shown in Patent Document 2 requires troublesome rail laying work as described above, the construction work is troublesome, and it is difficult to install the work by retrofitting. In addition, the underfloor storage device of the same document is that a predetermined number of carts are connected and integrated into a specific shape, so that the number of carts is specified and it is virtually impossible to change the number of carts. is there. For this reason, the optimal storage capacity cannot be secured according to demand, etc., and after construction, even if you want to increase the storage capacity, you cannot increase the number of trolleys and change the storage capacity after construction. There was a problem that could not be dealt with. In addition, since the entire shape of the underfloor storage device of the same document is specified, it is difficult to appropriately match the shape of the underfloor space.

  This caster (19) is attached to four places on the back surface of the base plate.

  The rotation fulcrum plate (40) is composed of a softwood plywood having a square shape in plan view. The length of each side of the rotating fulcrum plate (40) is equal to the length of the inner side (21) of the carriage (10) and is set to about 300 mm, and the thickness of the rotating fulcrum plate (40) is 24 mm. Is set to

  The rotation fulcrum plate (40) is attached to the support legs (2) and (2) via the fulcrum plate receiving member (41) so as to be rotatable about its axis.

  Here, the rotation fulcrum plate (40) may be attached to the support leg (2) in advance or may be attached later. In the case of retrofitting, the rotating fulcrum plate (40) is composed of two or more divided pieces, and the divided pieces are assembled and integrated so as to surround the support leg (2) from the outside to form a predetermined shape. What is made to do is used.

  The rotation fulcrum plate (40) is not limited to a so-called plate shape, and may have a frame shape in which an outer frame is formed in a predetermined shape such as a square.

  The four carriages (10) arranged so as to surround the four sides around the rotation fulcrum plate (40) are arranged such that the inner sides (21) thereof are in contact with the four sides around the rotation fulcrum plate (40). In addition, the front hypotenuse (25) is disposed in contact with the rear hypotenuse (25) between the adjacent carts (10).

  On the back side of the base plate of the carriage (10), rod-like fixed links (18) are respectively fixed in a state of being arranged along the front-rear direction, and the ends of each fixed link (18) are connected to each other. It is connected via (30). That is, the front end of the connection link (30) is connected to the rear end of the fixed link (18) in the preceding (front) carriage (10) so as to be rotatable about the vertical axis (in a horizontal plane), and the connection link ( 30) The rear end is connected to the front end of the fixed link (18) in the following (rear) carriage (10) so as to be rotatable about a vertical axis. Thus, the four carriages (10) are connected to each other in a state of being arranged around the rotation fulcrum plate (40), and are fixed in a quadruple shape. At this time, the carriage (10) is configured to be able to rotate and rotate in a horizontal plane with the center of the rotation fulcrum plate (40) as a fulcrum, and the inner side (21) of each carriage (10) The rotation fulcrum plate (40) is configured to rotate in synchronization with the rotation of the carriage (10) by being engaged with the outer side of the rotation fulcrum plate (40).

  Here, in this embodiment, the connection link (30) is made of a steel bar, and its length dimension is set to 459 mm, which is half of the support leg span.

  Furthermore, the connecting link (30) is set equal to the distance between the connecting link mounting positions of the fixed link (18), and a regular octagon is formed by the connecting link (30) and the fixed link (18). That is, the shaft support portions (31) at both ends of the connection link (30) are arranged at equal intervals along the circumferential direction, and are arranged at an equal distance from the center of the rotation fulcrum plate (40). Therefore, when each carriage (10) rotates, the running force is transmitted between the carriages (10) without difficulty, and each carriage (10) runs smoothly in a balanced manner along the circumferential direction. It is.

  In this quadruple underfloor storage device, the opening (5a) of the finished floor (5) is arranged at a position corresponding to one of the carts (10). Then, the vehicle is turned (circulated) by manual operation, and the desired carriage (10) is disposed at a position corresponding to the opening (5a) of the finished floor (5). Thereafter, articles are taken in and out of the desired carriage (10) through the opening (5a).

  By the way, in the underfloor storage device of the present embodiment, the four-unit shape restricts the swinging motion between adjacent carts (10), but simply connects two carts (10) to one connecting link (30). ) Is allowed to swing between the two carriages (10). For this reason, one trolley | bogie (10) is comprised with respect to the other trolley | bogie (10) so that rocking | fluctuation is possible between the serial state arrange | positioned in series, and the right angle state arrange | positioned at right angle. At this time, in the serial state, the front side (23) is brought into contact with the rear side (23) between the adjacent carts (10), and in the right angle state, the front oblique side is set between the adjacent carts (10). (25) abuts the rear hypotenuse (25).

  In the present embodiment, the allowable rotation range of the connecting link (30) with respect to the carriage (10) is limited to a range of 45 °, so that the allowable swing range between the two carriages (10) It is limited to the range of 90 ° between the right angle state. That is, the outer and inner swing restricting pieces (35a) and (35b) are fixed to both sides in the swing direction of the connecting link (30) on the back side of the base plate of the cart (10). When the connecting link (30) swings outward, the connecting link (30) is locked to the outer swing restricting piece (35a) to prevent further swinging outward. At the same time, when the inner link is rocked, the connecting link (30) is locked to the inner rocking restriction piece (35b), thereby preventing further rocking inward. In addition, in a state where the connecting link (30) is locked to the outer swing restricting piece (35a), the connecting link (30) is arranged orthogonal to the front and rear sides (23) and (23) of the base plate (20). At the same time, the connecting link (30) is configured so as to be orthogonally disposed with respect to the oblique sides (25) and (25) on both sides in a state of being locked to the inner swing restricting piece (35b).

  On the other hand, in this embodiment, in addition to the above-described quadruple shape, other shapes such as a six-strand shape and an eight-strand shape can be assembled.

  For example, as shown in FIG. 5 and FIG. 6, when assembling into a six-unit shape, the rotation fulcrum plates (40) and (40) are respectively rotated in the same manner as described above on the two adjacent support legs (2) and (2). Install freely. Further, six carts (10) are arranged in an oval or rectangular ring so that the two rotation fulcrum plates (40) (40) are located inside, and in this state, adjacent carts (10) are arranged. They are connected via a connecting link (30) in the same manner as described above.

  In this six-series shape, in the initial state shown in FIG. 6A, three trolleys (10) on one side are arranged around one rotation fulcrum plate (40), and the three trolleys (10 ) Is in contact with the three surrounding sides of one of the rotation fulcrum plates (40). Further, the remaining three carriages (10) are arranged around the other rotation fulcrum plate (40), and the inner side (21) of the three carriages (10) is arranged on the other rotation fulcrum plate (40). It is in contact with the three sides around. Further, in this state, adjacent carts (10) are arranged at right angles in the outer peripheral portion of the rotating fulcrum plate (40), and adjacent in the portion between the two rotating fulcrum plates (40) (40). The carts (10) are arranged in series.

  The finishing floor (5) has an opening (5a) at a position corresponding to any one of the carts (10).

  In the underfloor storage apparatus having the above configuration, a plurality of carriages (10) are circulated along an oval path by manual operation. For example, when the trolley (10) is held by hand and moved in the traveling direction from the initial state shown in FIG. 6 (a), each trolley (10) is circulated along an annular path. At this time, when each carriage (10) moves from the portion between the two rotation fulcrum plates (40) (40) to, for example, the outer peripheral portion of one rotation fulcrum plate (40), 10) is sequentially swung inwardly with respect to the subsequent carriage (10), so that the inner side (21) of each carriage (10) is shifted to one rotation fulcrum plate ( 40) Abuts sequentially on one side. Thus, the adjacent carts (10) rotate around one rotating fulcrum plate (40) in a right angle state, and the rotating fulcrum plate (40) follows the center of the cart (10) as a fulcrum. Rotate to. Further, when each carriage (10) moves from the outer peripheral portion of one rotation fulcrum plate (40) to a portion between the two rotation fulcrum plates (40) (40), each carriage (10) By sequentially swinging outward with respect to the subsequent carriage (10), the right-angle state is sequentially shifted to the serial state. In this manner, adjacent carts (10) travel in series between the two rotating fulcrum plates (40) (40).

  When this underfloor storage device is used, the carriage (10) is circulated and the desired carriage (10) is arranged at a position corresponding to the opening (5a) of the finished floor (5). And goods are taken in and out with respect to a desired trolley | bogie (10) through the opening part (5a).

  In the present embodiment, as shown in FIG. 5, an article storage box (60) may be arranged on the carriage (10), and the article may be stored and stored in the box (60).

  Thus, in this embodiment, it can be assembled by connecting four carriages (10) like a quadruple shape, or connecting six cars (6) like a hexagonal shape. Furthermore, the change between the quadruple shape and the hexagonal shape can be easily performed. That is, when changing from a 4-unit shape to a 6-unit shape, two carts (10), two connecting links (30) and one rotating fulcrum plate (40) are added, What is necessary is just to connect a trolley | bogie (10) suitably. On the contrary, when changing from the 6-unit shape to the 4-unit shape, the two carts (10), the two connecting links (30), and the one rotation fulcrum plate (40) are removed, and four carts are used. What is necessary is just to connect (10) suitably.

  On the other hand, in the present embodiment, as other shapes, for example, a long 8-strip shape shown in FIG. 7, a regular 8-strip shape shown in FIG.

  In the long 8-strip shape shown in FIG. 7, the carriage (10) is connected so as to circulate around the outer periphery of the three support legs (2) arranged side by side. That is, among the three support legs (2), the rotation fulcrum plates (40) are respectively attached to the two support legs (2) arranged at both ends, and the outer sides of the two rotation fulcrum plates (40). The adjacent carts (10) are connected via the connecting link (30) in a state where eight carts (10) are arranged in an oval shape.

  Further, in the regular eight-row shape shown in FIG. 8, the rotation fulcrum plates (40) are respectively attached to the four support legs (2) arranged side by side in the vertical and horizontal directions, and the four rotation fulcrum plates (40) of the four rotation fulcrum plates (40) are arranged. Adjacent trolleys (10) are connected to each other via a linking link (30) in a state where eight trolleys (10) are arranged in a quadrangular annular shape so as to hang over the outside.

  As described above, in the underfloor storage device of the present embodiment, the rotation support plate (40) is provided on the predetermined support leg (2), and the rotation support plate (40) is connected in an annular shape so as to be positioned inside. Since the plurality of carts (10) are caused to circulate while moving along the outer periphery of the rotation fulcrum plate (40), there is no need for rails for running the cart (10). Construction work can be performed easily. In addition, since a large-scale work such as a rail laying work is not required, it can be easily retrofitted even at the time of renovation.

  In addition, since the number of connected carts (10) can be arbitrarily set and the article storage capacity can be set freely, an optimal storage capacity can be ensured according to the demand of the user and the like. Furthermore, since the connection shape (travel path shape) of the carriage (10) can also be set arbitrarily, an appropriate travel path shape can be formed in accordance with the underfloor space, and no wasted space is formed in the underfloor space, Space can be used effectively.

  In addition, even after construction, simply by adding or removing components such as the cart (10) and the rotating fulcrum plate (40), the number of units connected to the cart (10) can be easily changed, and the article storage capacity can be increased. Since it can be increased or decreased, it is possible to reliably cope with a change in storage capacity after construction, and the product value can be significantly improved.

  Particularly in the present embodiment, the length of the connecting link (30) is set to ½ of the span of the support leg (2), and the longitudinal dimension (traveling direction length) of the carriage (10) is Since it is made to correspond to the span of the support leg (2), the number of connections and the connection shape of the carriage (10) can be set without being restricted by the dimensional relationship between the support leg span and the carriage size. The size of 10) can be secured sufficiently large, the flexibility with respect to construction increases, and the commercial value can be further improved.

  FIG. 9 is a cross-sectional view showing the periphery of a rotating fulcrum plate having a floor structure to which the underfloor storage apparatus according to the first modification of the present invention is applied. As shown in the figure, in the underfloor storage device, the carriage (10) is circulated by rotating the handle (70). That is, a square rotation fulcrum plate (40) is rotatably attached to a predetermined support leg (2) serving as a fulcrum of the carriage (10), and is integrated with the rotation fulcrum plate (40). The first gear (71) is fixed to the upper surface of the rotation fulcrum plate (40) so that it can rotate.

In addition, if the underfloor installation surface (1) has an uneven surface or soil, it can be made flat with concrete or mortar, or it can be laid with a floorboard to make a flat surface. Good to do. In addition, the laying board may be divided into two or more sheets. In that case, it is preferable to join the adjacent laying boards by phase-bonding or the like.

  The material of the floor support members such as the support legs (2) and the bundle is not particularly limited, and any material such as metal, plastic, wood, etc. can be used. For example, since many support legs made of metal or plastic are formed with a circular columnar section, it is easy to rotatably attach the rotation fulcrum plate (40) to the columnar section. In many cases, the cross section is rectangular in shape. Therefore, when the rotation fulcrum plate (40) is attached to the pedestal, the cylindrical member is attached to the outer periphery of the pedestal and the rotation fulcrum plate (40) is attached to the cylindrical member. Should be attached.

  The material of the rotating fulcrum plate (40) is not particularly limited, and any material such as a wooden material, a metal material, or a plastic material can be used. Also, the shape of the rotation fulcrum plate (40) is not particularly limited, but when rotating in synchronization with the carriage (10), it is preferably constituted by a polygon such as a square. Furthermore, when not synchronizing with a trolley | bogie (10), it is good to comprise by a circular thing and to move a trolley | bogie (10) so that it may slide along an outer peripheral edge.

  The thickness of the rotating fulcrum plate (40) is not particularly limited, and it is preferable to set the thickness to about the same as the thickness of the base plate (20) in the carriage (10). When using a square thing like the said embodiment, it is good to set the length of one side of a rotation fulcrum board (40) equal to the length of the inner side (21) of a base plate (20). Specifically, as the rotation fulcrum plate (40), a square plate having a thickness of 15 to 30 mm and a side length of 200 to 300 mm, a circular plate having a diameter of 200 to 300 mm, or the like is preferably used. it can.

  When the rotation fulcrum plate (40) is rotatably attached to the support leg (30), the support leg insertion hole in the rotation fulcrum plate (40) is slightly larger than the support leg (30) so that the rotation can be smoothly performed. It is good to form. However, if the insertion hole is formed too large, eccentricity or the like occurs, which is not preferable.

  The material of the base plate (20) of the carriage (10) is not particularly limited, and for example, a wooden or synthetic resin material can be suitably used.

Further, as the caster (19), a bearing such as a ball bearing is interposed between a shaft support portion between the wheel portion and the mounting portion and a shaft support portion between the wheel shaft and the wheel so that the turning and rotation can be smoothly performed. It is good to use.

  The size of the wheel in the caster (19) is not particularly limited, but a wheel having a diameter of 30 to 100 mm, more preferably 50 to 75 mm may be used. In other words, when the wheel diameter is too large, the height of the base plate is increased, and accordingly, the storage space is reduced. On the other hand, when the wheel diameter is too small, a particularly heavy article is mounted. There is a possibility that the running stability is lowered and it is difficult to run the carriage (10) smoothly.

  The material of the connecting link (30) is not particularly limited, and those made of metal, synthetic resin, wood, or a composite member thereof can be suitably used.

  The connecting link (30) may be attached to either the back surface side or the front surface side of the base plate (20), but if attached to the front surface side, there is a risk of hindering when an article is mounted on the base plate (20). Therefore, it is desirable to attach it to the back side. Of course, when the connecting link (30) is attached to the surface of the carriage (10), the storage space is reduced, but a plurality of protruding members are attached to the surface of the carriage to prevent the rotation of the connecting link (30). You may make it support, Furthermore, you may make it arrange | position the plate-shaped body for goods mounting, etc. on a projection member. Further, the movable range of the connecting link (30) in the base plate (20) may be cut out.

  The length of the connecting link (30) is not particularly limited, but by setting it to 1 / n times the support leg span (n is an even number), optimally 1/2, the carriage (10) Smooth circulation can be achieved.

  Moreover, the shape, material, etc. are not specifically limited as for the article | item storage box (60) mounted in a trolley | bogie (10) as needed. For example, a material made of wood, resin, paper, metal, a composite material thereof, a cube shape, a rectangular parallelepiped shape, a polygonal column shape, a cylindrical shape, an elliptical column shape, a composite shape thereof, or the like is preferably used. be able to.

  The size of the article storage box (60) is not particularly limited, but it is preferable to use a size that does not protrude from the carriage (10).
